Product information

Description

Side-mount magnetic reed switch KONTAKTRON BOCZNY KN-M04 is a mechanical magnetic contact sensor designed to detect the open or closed position of doors and windows. The sensor consists of a reed contact enclosed in a housing that changes state when a magnetic field from a separate magnet is present. Its side-mount design allows installation on the edge of frames where surface mounting is impractical or where a discreet contact point is required. The device is suitable for integration with alarm systems, access control panels, and basic status monitoring circuits in residential and commercial buildings.

Advantages

The side-mount form factor enables installation on narrow frame edges and profiles, providing a compact and unobtrusive sensing point. The reed contact mechanism is passive and requires no internal power to detect a magnet, which makes it reliable and energy-efficient when used with external control equipment. The simple mechanical construction offers long-term durability when used within its rated environment and allows straightforward wiring and replacement.

Suitable for

  • Monitoring door and window open/closed status in alarm systems
  • Basic access control and entry detection
  • State feedback for automation or building management systems
  • Low-voltage security and monitoring circuits in residential or commercial installations

Key specifications

  • Mounting style: side/edge mounting suitable for frame profiles
  • Contact type: magnetic reed contact (normally closed or normally open depending on wiring and magnet position)
  • Operating principle: magnet-actuated mechanical switching
  • Suitable environment: indoor installation, standard residential and commercial conditions
  • Connection: simple two-conductor wiring for integration with security panels or monitoring circuits

How to use

Install the reed switch on the frame edge where the magnet will align with the contact when the door or window is in the closed position. Secure the sensor using screws or adhesive appropriate for the surface, ensuring correct alignment and gap tolerance between sensor and magnet. Connect the two conductors to the alarm panel or control input according to the system wiring requirements, observing polarity if specified by the controller. Test the installation by opening and closing the door or window and verifying that the control system registers the change in state.

Usage recommendations

Place the magnet as close as the manufacturer’s recommended gap allows to ensure reliable switching; avoid mounting near strong external magnetic fields or metal obstructions that may affect operation. Use appropriate low-voltage wiring and follow local electrical codes when integrating the switch into alarm or access control systems. For outdoor or high-humidity environments, select an enclosure or location that protects the device from direct exposure to weather.
